I initially chose a DM8148 processor with the intention of having the DSP run a real-time OS controlling I/O (GPIO, CAN, SPI) and the ARM running linux providing network communication, ftp upload, file-storage, etc. Now I appear to be a bit stuck.
My questions are as follows:
1) I read on wikipedia that the means for having the DSP control I/O is not supported that the DSP is merely to be used as a video co-processor. Is this true?
Assuming that #1 is true, then I need to look into a means for having an RTOS on the ARM while still supporting network communication, ftp upload, file storage etc. on the ARM. So question #2
2) Does anybody have any experience with RTOSes on the DM8148 reliably performing these functions? My controller runs a 5000 hp motor, so reliability is crucial.
Thanks,
